Rehabilitation treatments applied to a local road prone to terrain subsidence from mining excavation should be designed considering cost-efficient and effective reinforcement solutions. In the analysed case, a glass-fibre mesh was applied under asphalt concrete layers in 2008, in one lane while another was left without the reinforcement. The main objective of this paper was to investigate the effectiveness of reinforcement by analysing the amount of produced on the pavement and the influence on pavement deflection. It was found that the reinforcement retracted the number of cracks, however, did not affect the bearing capacity. The influence of the applied geosynthetic was manifested in the values of the radius of curvature. The overall technical state of the road requires immediate treatment and the applied reinforcement proved obsolete because in this particular case of road located in the mining active terrain the glass fiber mesh did not prolong the life of the pavement.
